     FDTD geometry mesh showing a wire dipole antenna model.
 
-The antenna is fed using the ``#tranmission_line`` command. The one-dimensional transmission line model virtually attaches to the dipole at the gap between the arms. The antenna has an input impedance (:math:`Z_0`) of 73 Ohms specified in the ``#tranmission_line`` command. The transmission line uses a Gaussian waveform with a centre frequency of 1GHz.
